Özet:

This research aims to synthesize a trigeneration system for a "solar house" based on an autonomous small solar photovoltaic plant, which could meet the year-round private consumers' needs for heat and cold supply.The climatic data on the Middle East countries, such as Iran, Saudi Arabia, the United Arab Emirates, Turkey, Syria, and Iraq, were used. Day and night air temperatures in different regions of these countries throughout the year and the total daily radiation, which comes onto a horizontal surface area, were determined. The obtained results revealed that the entire territory of the Middle East is suitable for the development of solar power supply. Seasonal and daily temperature fluctuations require the year-round use of artificial cold for air conditioning and heating of premises. As a result of the analysis, the generalized circuit solution of the small integrated trigeneration system, based on the photovoltaic solar station, was synthesized. Additional solar collectors with a water heater-accumulator provide hot water supply. Air conditioning and heating are provided by a refrigerating machine. The time of modes change is determined by ambient temperature, which does not correspond to comfortable temperature in particular premises. The temperature mode in premises is maintained by the fresh air flow from the active ventilation system, cooled or heated in heat-exchanger of a machine. To harmonize the operation of all elements of the system, the toolkit for determining thermal loads and temperatures modes on premises and elements of the trigeneration system were developed. The study makes it possible to argue that "solar houses" can solve energy, environmental problems of regions, satisfy the social needs of the population in the Middle East countries Author Biographies Larisa Morozyuk, Odessa National Academy of Food Technologies Kanatna str., 112, Оdеssа, Ukraine, 65039 Doctor of Technical Sciences, Professor Department of Cryogenic Technique
